Depending on the make and model you drive, you might have disc brakes on the front and drum brakes on the rear, or you could have four-wheel disc brakes. These are becoming more and more common today. However, regardless of the configuration, you should not have a loud noise coming from the rear brakes. This indicates that something has gone wrong, and there are several potential culprits. Your rear brakes work similar to the front brakes. The master cylinder sends pressurized fluid through the brake lines. If you have rear drum brakes, the fluid causes the actuator to push the brake shoes outward, where they press against the inside of the drum. In the case of rear disc brakes, the fluid activates the caliper, which then squeezes the caliper between two brake pads. This is identical to how your front brakes operate, but the pads are generally smaller than those used on the front. This is because most of the stopping power in your car is generated in the front. However, your rear brakes are just as important as the front, and if you’re noticing a loud noise from the rear during braking, it could be a number of different things, depending on the type of noise and when it occurs.
A top-rated mobile mechanic will come to your home or office and will inspect your rear brakes. This inspection will include the drums and shoes or the rotors and calipers. It should also include the brake lines and other components. The mechanic will then provide a detailed inspection report that includes the scope and cost of the necessary repairs. The mechanic will inspect your rear brake pads, the rotors, calipers, and the brake lines. It may be necessary to remove one or both rear wheels for a visual inspection. It may also be necessary to test drive the vehicle if the source of the problem is not immediately apparent in order for the mechanic to verify any and all noises.
The mechanic will visually inspect the rear brakes, as well as other components that might be causing the noise you’re experiencing. It might be necessary for the mechanic to test drive the vehicle in order to duplicate the noise and better diagnose the problem.
